Different calculations to the Subjects mol and Calculation with Large Figures.

1. Person A receives One Daily wages of 1000.-, Person B One Annual salary of a half Mol French. Who has The Greater Annual salary? Adopted: Person A work to 365 days In the year. In order to which Factor earned The Person more as The Other Person?
2. One of them mol French will be Equivalent to on The Population of the world (about. 8 Billions of dollars Persons) distributed. How a lot French receives each Person?
3. The Distance The Sun – Earth is about. 150 Millions Kilometers. How many Atoms with a Diameters of in each case 10^-10 m would be necessary, to These Distance How One Woven fabrics of cotton, knitted or crocheted to be removed. Indication The required Atoms in mol.
4. The pH-Value Right now. seven That's right., that for each Litre Water(-Particles) 10^-7 mol more specific Particles of water (H₃O⁺) Available. How many Particles are This So what do you mean? Specifically? And then … How many 'normal' Particles of water are In fact, of which:?

Lösung:

1. Annual salary Person A: 365·1000.- = 365'000.- = 3.65·10⁵
   Annual salary Person B: 0.5·6.022·10²³ = 3.011·10²³
   Person B receives a lot more Salary. Factor: 3.011·10²³ / 3.65·10⁵ = 8.25·10¹⁷
2. 6.022·10²³ French/ 8·10⁹ = 7.5·10¹³ French for each Person
   Or in Words: about. 75'000 Billions of dollars French for each Person
3. 150 The Commission's proposal km = 150·10⁶ km = 150·10⁹ m
       150·10⁹ m / 10^-10 m = 1.5·10²¹ Atoms
       Number of mol = 1.5·10²¹ /6.022·10²³ = 0.0025 mol
       Or in Words: about. 1/400 mol
4. 1 mol H₂O corresponds to 18 Grams, 1 Litre Water So what do you mean? 1000/18 = 55.5 mol
       10^-7 mol = 10^-7 · 6.022·10²³ = 6.022·10¹⁶
